2021 Toyota Corolla Engine Problems

The Clutch Slave Cylinder needs replacement

Engine maintenance required, call dealer. The engine coolant bypass valve needs to be replaced. Known issue in Toyota corolla’s yet no recall to remedy the repair.

I turned on the vehicle and an Engine Maintenance Required light and warning went off on my car. I noticed the warning would only come up once I turned on the A/C so I presumed it was an issue with the Coolant Bypass Valve

I was driving yesterday morning to work in freeway and a Message appeared in the dash saying Engine Maintenance Required. The message stills appears and it’s a safety issue that needs to be addressed by Toyota for defective parts or defective car and Toyota needs to replace my current vehicle for a new car. Furthermore this is a safety issue for me and others while the car is running.

Coolant bypass valve broken

Engine maintenance required P268115 engine coolant bypass valve

The car shows the message “Engine Maintenance Required” that leads to the coolant bypass hose being bad.

The engine maintenance required sign popped up on my 2021 Toyota Corolla and took it to a dealer to get it diagnosed and they reported back it was the coolant bypass valve. They want 1,000$ to fix the issue even tho the person I was dealing with at the dealer shop said it’s happening to all the corollas from 30,000 miles to 50,000 miles .

Coolant bypass valve has failed. AutoNation Toyota in Cerritos has verified issue. This issue has caused potential engine overheating, engine maintenance required warning light has popped up in my vehicle, was told by AutoNation that my vehicle is not covered for this repair and I will have to pay out of pocket.

Vehicle: 2021 Toyota Corolla Apex, 2.0L Engine Component Failure: The Engine Coolant Bypass Valve (also called Water Valve) malfunctioned. Its plastic housing cracked and leaked coolant, corroding the electrical connector. This prevents proper electronic control of engine temperature. The failed component is available for inspection if removed. Safety Risk: This issue poses a safety risk due to potential engine overheating. Overheating can lead to sudden loss of power or engine stall while driving, increasing the risk of a collision, especially at high speeds. A roadside breakdown in unsafe conditions is also a risk. Confirmation: A Toyota dealership service center confirmed the problem, diagnosing it as a leaking coolant bypass valve requiring replacement. Inspection: The vehicle was inspected by a Toyota dealership technician. It has not been inspected by the manufacturer, police, or insurance representatives. Warnings/Symptoms: The primary symptom was the "Engine Maintenance Required" message illuminating in the instrument cluster. This first appeared approximately [State how long ago, e.g., "3 weeks ago" or "at 45,000 miles"]. No other immediate symptoms like visible leaks or temperature fluctuations were initially noticed, though a leak was confirmed later.

On my 2021 Toyota Corolla SE at 43k miles the “service engine needed” notification came on. As I’m researching it’s a known issue with these models and RAV4 models. The cooling valve is needing to be replaced and Toyota does not cover it costing us about $500-$700 at the dealership.

My 2021 Toyota Corolla has 43k miles at this moment and the engine coolant bypass valve went out prematurely. There should be a recall on this part because a lot of people are having issues with this part on these cars at such low millage. Thanks

I recently purchased a 2021 Toyota Corolla SE. After a few days the "Engine Maintenance Required - See Dealer" notification appeared. See as it was purchased very recently, I assumed this was the oil maintenance light, and reset it. Later that day, it came back, and I reset it a different method under the assumption I did it wrong. The next day it was back, and that is when I realized it must be something else. So I started doing some research and found lots of other people have had this same issue: 2020-21 Corolla, greater than 30k miles, usually less than 60k, and while the Check Engine Light *DOES NOT TURN ON* the car is throwing an error code: P268115 - Engine Coolant Bypass Valve. Sure enough, I have the codes pulled and I have that code showing up. So I took it to the local Toyota Dealership. They stated that the issue was not a warrantable, so I would likely have to pay out of pocket. After a slight fuss, they agreed to fix it as a "one-time goodwill gesture, performed in the interest of customer satisfaction..." So in the end, they did fix it; I did still have to pay for a diagnostic of the issue which is frustrating, especially since I was dead on in my analysis of the issue. To answer the guideline questions: Engine Coolant Bypass Valve Leaking engine coolant could cause the engine to overheat, which can lead to fires, not exactly ideal. It can also cause electrical shorts, leading to more issues. Yes. Lancaster Toyota confirmed the issue. Yes, Lancaster Toyota confirmed that the part was faulty. They appeared shortly after buying the car. There were no error lights like I'd expect, but there was the constantly appearing "Engine Maintenance Required - See Dealer" message which the Owner's Manual states is simply the 5000 mile Oil Change warning. Hidden behind this message is the error code P268115.

Apparently my car's Engine Coolant Bypass Valve is broken and it's a common case with my car's model that's made after 2020. Seems like it there's a need a recall for such a thing since it's a defective part they knew about since my car was screaming at me for an engine maintenance. However, the check engine wasn't on. I went to Toyota at Elk Grove, CA and knew what the issue was pretty quick and charging me $700 to get it replaced. I feel like it's intentionally being handled poorly so they keep charging me 700 every few years to replace a $80 part. As well my story is very common with other customers of Toyota Cars made after 2020. I wanted to report this since that's potentially harmful to put out a car that could have engine problems easily. Especially it's a fairly newer car. Also, they have yet to replace the part for the known recall on this vehicle.

Engine Maintenance Required message came on. Took the vehicle to the dealership and was told that it was the Cooling Bypass Valve. The service advisor said he knew what the problem was before even looking at the vehicle but still wanted to run a diagnostic and charge $800-$900 for the repair. I was told my vehicle was no longer under warranty.

Engine code P2681(15) which after lookup is the coolant bypass valve which is a common faulty part that Toyota seems to not care about and charge upwards of 700$ at the dealer to fix. I took the part out and it indeed has a crack around the case

My car reached 52,254 miles and I got a engine maintenance required a scary message I have never seen before I thought it was the oil maintenance one but it’s not I keep dismissing the message because I can’t see my speed and it stays in the way I have realized that if I start the car with AC on the message pops up but if I don’t have ac on and start the car it never appears unless I turn on the ac as the car is already on so it seems to be the coolant valve bypass I received the error message as I was parked for no longer than 40 seconds at most

Collant by pass malfuntion 2 time

After hitting 45k miles my engine light turned on and required a coolant bypass valve replacement. This issue has occurred for all Toyota Corolla drivers and rav4 drivers I have came in contact with. This issue should be resolved my car is only 3 years old and should not require pricey engine repairs.

Engine coolant bypass valve short to battery. Throwing code - P2681-15 at 33,000 miles.
